Do you want to display your friends' Twitter statuses/updates on your conky desktop system monitor? If you want to then I'll show the way to easily do it without having to install additional modules. Here's how:

You can provide the number of statuses that you want to display by editing item_titles. Like I changed mine to 8.

The number 20 indicates that the RSS feed will update at 20 minute intervals. I would suggest that you keep it above 20 minutes especially if you are using other Twitter desktop clients in order to avoid reaching the API limits and to stay away from congestion.
